摘　　要：文章主要介绍了如何使用Proppy HF软件对业余无线电信标台接收强度进行预测和使用VOACAP软件对短波传播覆盖进行预测分析,在二者分析基础上使用Kiwi SDR设备进行业余无线电信标台的实际接收测试。通过上述方法,分析了不同位置、不同频率、不同时段的信号对业余无线电短波通联的影响,为业余爱好者进行远距离无线电通联提供技术参考。This paper mainly introduces the prediction of reception intensity of amateur radio beacon stations by Proppy HF software,and the prediction analysis of shortwave propagation coverage by VOACAP software.Then actual reception tests of amateur radio beacon stations based on these two analyses are conducted using Kiwi SDR equipment.Through the above method,the amateur radio shortwave communication effect of signals of different positions,frequencies and different periods is analyzed,which provides a technical reference for amateurs to carry out long-distance radio communication.
